Title: Coaxial type flat speaker
Inventor: FUKUYAMA TATSUO
IPC: H04R9/06
Filed: 1983-05-20
Abstract: PURPOSE:To improve the durability of a tweeter by providing through-holes to flow air at side faces of a housing containing the tweeter so as to improve the heat irradiation of the tweeter. CONSTITUTION:The housing 17 for containing the tweeter is formed cylindrical as a whole and the through-hole 17a is provided at several positions on the circumference. The heat generated at the coil part of a disc coil 4 is conducted almost to a plate 5 and a yoke 7. The heat of the yoke 7 is conducted to the plate 14 through the cast 17 partly and since the plate 14 is heated by the head of the coil part of the coil 4, the heat dissipation in this direction is not expected. Since the through-holes 17a are provided to the case 17a, however, the heat like this is carried away to the external part of the case 17 by the air flowing through the through-holes 17a in a large quantity. Thus, the heat generated to the coil part of the coil 4 is dissipated to the plate 5, the magnet 6 and the outer side face of the yoke 7 and also the through-holes 17a of the case 17, then the temperature rise of the coil part of the coil 4 is suppressed low.

Title: Answer detection controlling system of automatic exchanger
Inventor: NISHIKIORI SHIYOUGO
IPC: H04M3/02
Filed: 1981-06-12
Abstract: PURPOSE:To control plural extension lines with one call signal trunk, by installing an answer detecting section which detects that at least one terminal out of plural terminals makes answer. CONSTITUTION:When a call arrives, it is checked from the content of a path memory section 6 that whether other calling telephone sets TEL are connected to a call signal trunk RGT or not. When other telephone sets TEL are connected to the trunk RGT, a controlling circuit 5 catches the paths between the calling telephone sets TEL and the trunk RGT and stores the caught information in the path memory section 6, and, at the same time, closes a switcg SW. Other incoming calls are also processed in the same way. On the other hand, when at least one of the telephone sets TEL makes an answer, the said answer is detected at a trunk answer detecting section 1 and an IR is stopped. At the same time, the controlling circuit 5 discriminates the answering telephone set. Then, a section between paths which discriminate the answer stored in the path memory section 6 is released and the path information is reset, and then, the switch SW is closed. Answers of other telephone sets are also processed in the same way.

If a timer value comparing circuit 3 operates after the tape speed adjusting circuit 4 operates, the phase detecting circuit 5 performs the 2nd tape speed control. In this case, a signal of, for example, every quarter frame is received from tape timer circuit 1 and the tape speed adjusting circuit 4 is indicated so as to shift the timing of a control signal in the positive or negative directions by a quarter frame. Thus, the probability of coincidence increases in the 2nd operation.

IPC: H01J27/22
Filed: 1981-06-12
Abstract: PURPOSE: To make ions with a high luminance to be produced with an ion source, which is most suitable for an ion micro analyzer, by evaporating and ionizing an ionized substance by making electrons of high density to concentrically bump against the microscopic area of the said ionized substance.  
     CONSTITUTION: The liquid of an ionized matter reaching to the extreme end of a case 1 maintains to have a shape caused according to the balance between the electrostatic stress of an electric field produced by a voltage applied across the case 1 and an electrode 5, and the surface tension of the liquid itself. Since the above shape is almost like a cone, the above electric field is concentrated on the angular end of the conical liquid. Next, produced ions are accelerated by a strong electric field existing around the pointed end of the liquid cone, pass through an opening 4 of the electrode 5, and are further accelerated by the effect of an accelerating electrode 9, thereby obtaining an ion beam having an injection angle regulated with a diaphragm plate 10. As a result, electrons with high density can be made to bump concentrically against the acutely angular end of the conical liquid ionized matter, and ions with a high luminance can be produced from the microscopic part.

Patent JP-S60233421-A (JP)
Title: Cooking stove burner
Inventor: ISHIBASHI NOBORU
IPC: F23D14/06
Filed: 1984-05-07
Abstract: PURPOSE:To make a turn-down range stable and wide, and to secure the safety even in the case of blow-out, by forming constantly a pilot flame in a part of a burner port by using a pilot flame gas supply pipe separately from a main gas circuit, and by providing a detecting element opposite to said flame. CONSTITUTION:A solenoid valve 19 is opened forcedly by operating a cock 12, and thereby ignition is made in burner ports 9 and 9'. Since the upstream side of a burner port passage 8' is closed substantially on the occasion, little gas flows from a main gas supply pipe 11 into the burner port 9' for a pilot flame. A thermocouple 18 is heated by the pilot flame 21 in the burner port 9', so as to generate an electromotive force and thereby to make the solenoid valve 19 opened by itself and held in this state. While the quantity of heat of a main flame 20 is controlled by the turn-down operation of the cock, the pilot flame 21 is maintained in a fixed state constantly during the operation for employment, so as to heat the thermocouple 18. Therefore the pilot flame is maintained stable irrespective of the degree of the turn down. Moreover, keeping warm or stewing can be conducted by the pilot flame alone, while the main flame is extinguished. When the pilot flame is extinguished, the excitation of the solenoid valve 19 is canceled, and thereby a gas circuit is closed.
